Shrub rose plant named ‘WEKclaflobo’

ABSTRACT

A new variety of Shrub rose suitable for garden decoration, having flowers of ever-changing yellows and blushing pinks coloration.

Classification: The present invention relates to a new Rosa hybridaplant.

Variety denomination: The new plant has the varietal denomination‘WEKclaflobo’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Shrub Rose. Ithas an undisseminated seedling of my creation as its seed parent withthe following genetic origin Santa Claus×Flower Carpet and as its pollenparent the variety known as ‘WEKplapic’ (U.S. Plant Pat. No. 11,517).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combination of characteristics: its very longfoliaceous appendages on the surface of the bud, its ever-changingyellows and blushing pinks coloration, its red suffusion on the innersurface of the sepal that appears as the flower ages and its redsuffusion on the under side of the mature leaf. The plant has a bushymoderately spreading growing habit, suitable for outdoor gardendecoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Pomona, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘WEKclaflobo’ maybe asexually propagated by cuttings, budding and grafting. The buddingand grafting successfully occurred on the plant/rootstock Rosa hybridacv. ‘Dr. Huey’ (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, anundisseminated seedling of my creation by the following combination ofcharacteristics: whereas ‘WEKclaflobo’ bears medium sized flowers (about6.5 to about 9.3 cm. in diameter) of ever-changing yellows and blushingpinks coloration, the undisseminated seedling bears significantlysmaller flowers of yellow coloration. The new variety is classified as ashrub rose with a bushy moderately spreading medium height growinghabit, whereas the seed parent is classified as a floribunda rose with asignificantly smaller and rounded growing habit.

The new variety may be distinguished from its pollen parent, ‘WEKplapic’by the following combination of characteristics: whereas ‘WEKclaflobo’bears single flowers (about 5 to 6 petals) of every-changing yellows andblushing pinks coloration, ‘WEKplapic’ bears semi-double flowers withsignificantly heavier petalage (about 9 to 12 petals) of ivory edged redcoloration. The new variety is classified as a shrub rose with a bushymoderately spreading medium height growing habit (about 60 to about 80cm. spread at the widest point), whereas the pollen parent is classifiedas a floribunda rose with a upright medium height significantly morespreading growing habit (about 105 to about 130 cm. spread at the widestpoint).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is thepollen parent ‘WEKplapic’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. Throughout this specification, color references and/or valuesare based upon the Colour Chart of The Royal Horticultural Society(1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Pomona, Calif. in the month of October.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

FLOWER

The new variety sometimes bears its flowers singly, usually in clustersof three to six or more per stem. Flowers may be borne in regularrounded clusters on strong somewhat short stems (about 10 to about 38cm). Outdoors, the plant blooms abundantly and nearly continuouslyduring the growing season. The flowers have a moderate fruity toapple-like fragrance.

BUD

The peduncle is about 1.9 to about 3.5 cm. in length, of slender caliper(about 0.15 to about 0.2 cm. in diameter), and usually erect. It issomewhat rough, with some stipitate glands. Peduncle color is between144A and 146B often moderately suffused, especially on the side exposedto the sun, with between 183A and 187B.

Before the calyx breaks, the bud is about 0.9 to about 1.5 cm. indiameter at the widest point, about 1.5 to about 2.1 cm. in length, andpointed in shape with a somewhat conspicuous neck. The surface of thebud bears few very long foliaceous appendages and some stipitate glands,usually with slender entire foliaceous parts extending beyond the tip ofthe bud about ¾ or more of its length. Bud color is between 146B and144A often heavily suffused, especially on the side exposed to the sun,with between 183A and 187A.

The sepals are about 2.4 to about 3.2 cm. in length and about 0.6 toabout 1.1 cm. in width at the widest point. The outer surface color ofthe sepal is between 146B and 144A often heavily suffused, especially onthe side exposed to the sun, with between 183A and 187B. The innersurface color of the sepal is between 137B and 144B. After the sepalsopen, the inner surface color is often heavily suffused, especially onthe area exposed to the sun, with between 187A and 187B. The sepals arecovered with fine wooly tomentum; sepal margins are lined with somestipitate glands and few hairs.

The receptacle of the flower is of medium length (about 0.5 to about 0.7cm.) and average in caliper (about 0.5 to about 0.6 cm. in diameter).The receptacle is globular to moderately rounded in form. Its surface issmooth with thick fleshy walls. The receptacle color is between 146B and144A often heavily suffused, especially on the side exposed to the sun,with between 183A and 187B.

As the petals open (after the calyx breaks), the bud is about 1.3 toabout 2.1 cm. in diameter at the widest point, about 2.0 to about 2.6cm. in length, and moderately ovoid to pointed in form. On the undersurfaces of the newly opened petals, the color at the base of the petalis between 6C and 7C that gradually suffuses toward the center of thepetal to between 18A and 20C, usually heavily blushed with between 53Band 53C to sometime as dark as between 187A and 187B. There is novisible change in coloration at the point where the petal attaches. Onthe upper surfaces of the newly opened petals, the color at the base ofthe petal is between 9B and 7A that gradually suffuses toward the centerof the petal to between 19A and 20A, usually heavily blushed toward thepetal edge with between 46A and 53B to sometime as dark as between 187Aand 187B. There is no visible change in coloration at the point wherethe petal attaches.

BLOOM

When fully open, the bloom ranges from about 6.5 to about 9.3 cm. indiameter. Petalage is single with about 5 to 6 petals and about zero toone petaloid irregularly arranged. When partially open, the bloom formis moderately cupped to somewhat ovoid, and the petals are looselyspiraled to cupped with petal edges somewhat reflexed outward. Whenfully open, the bloom form is more flat to somewhat cupped, and thepetals are loosely cupped with petal edges somewhat reflexed outward.

PETALS

The substances of the petals is moderately heavy and of medium tosomewhat thick thickness, with upper surfaces somewhat satiny toslightly shiny and under surfaces slightly shiny to matte. The petalsare about 3.2 to about 4.5 cm. in length and about 2.9 to about 4.1 cm.in width at the widest point. Petal margins are entire. The petals aremoderately obovate in shape with rounded to sometimes mucronate apices.

Petaloids are about 1.9 to about 2.7 cm. in length and about 0.8 toabout 1.0 cm. in width at the widest point. Petaloids are irregularlyshaped somewhat subulate to oblanceolate with rounded apices.

NEWLY OPENED FLOWER

On the under surfaces of the newly opened petals, the color at the baseof the petal is between 3D and 2C that gradually suffuses toward thecenter of the petal to between 18B and 19B, usually heavily blushed withbetween 53C and 52A to sometime as dark as between 187A and 187B. Thereis no visible change in coloration at the point where the petalattaches. On the upper surfaces of the new opened petals, the color atthe base of the petal is between 6C and 15D that gradually suffusestoward the center of the petal to between 15D and 20D, usually heavilyblushed toward the petal edge with between 53C and 52A to sometime asdark as between 187A and 187B. There is no visible change in colorationat the point where the petal attaches.

The under and upper surface color of the petaloids are similar incoloration to the upper and under surfaces of the petals.

The general tonality of the newly opened flower is between 6C and 15D atthe base of the petal that gradually suffuses toward the center of thepetal to between 15D and 20D, usually heavily blushed toward the petaledge with between 53C and 52A to sometime as dark as between 187A and187B.

THREE-DAY-OLD FLOWER

The upper surface color of the petals is between 155C and 155D usuallyheavily blushed on the entire petal surface with between 61C and 58C tosometimes as dark as between 60B and 60A. The under surface color of thepetals in similar to the upper surface color except that the blushedcoloration does not cover the entire surface. There is no visible changein coloration at the point where the petal attaches on the upper andunder surface.

The under and upper surface color of the petaloids are similar incoloration to the upper and under surfaces of the petals.

The general tonality of the three-day-old flower is between 155C and155D usually heavily blushed on the entire petal surface with between61C and 58C to sometime as dark as between 60B and 60A.

On the spent bloom, the petals usually drop off cleanly.

In October in Pomona, Calif., blooms on the bush growing outdoorsgenerally last about four to five days. Cut roses from plants grownoutdoors and kept at normal indoor living temperatures generally lastabout four to five days.

The color of the branches is between 146B and 146A. They bear some largeprickles which are of similar size and shape of the large prickles onthe major stems; prickle color is between 164C and 164B. The branchesbear some small prickles of similar shape and coloration.

The color of the new shoots is between 146B and 146A often moderatelysuffused with between 183B and 187B. They bear some medium size prickleswhich are of similar shape to the large prickles on the major stems. Themedium size prickles are about 0.3 to about 0.5 cm. in length. Pricklecolor is between 153A and 151A usually heavily suffused with between187B and 187C. The shoots bear some small prickles of similar shape andcoloration.
